2000 Mercury Mountaineer transmission failure vehicle has only 64,000 miles, transmission has been power flushed by our local Ford dealership with no correction, we were told the problem was shift flare, with the o/d light flashing is common with all 5r55e transmissions with 4. 0l v6 engines. We were told it would be best to replace the transmission with a factory remanufactured unit, rather than try to repair the old transmission at a cost of $2500. 00 to $3000. 00 dollars. We are now to a point where we cannot drive the vehicle any great distance other than right around town. Assistance from Ford would be greatly appreciated this vehicle is the fourth Ford product we have owned, we now have doubts about our 2005 f150 4x4 supercrew we use to pull our 26' travel trailer approx 4860lbs. Our vehicle is in wonderful condition and we do not want to get rid of it, the manufacture needs to step up and help all the loyal Ford owners that have believed in there products for many years.
While driving at low speeds, the vehicle down shifted to low range. The 4wd and overdrive lights where flashing and whining along with an alarm sound coming from the dash. The engine was shut off and the key was removed, but the whining sound continued. The consumer disconnected the battery and the noise stopped.
